My screen won't turn off

Hi!

I have a 27" iMac (late 2015) , running macOS High Sierra 10.13

Since I upgraded to High Sierra, my screen stays on all the time.

I have set up the following under ENERGY SAVER : Turn off display after 15 minutes

Screen saver is set to turn on after 20 minutes, so technically , shouldn't see the screen saver

Any ideas? I'm pretty sure its no good for the screen to be on 24x7.

I tried changing the sliders to 20 minutes back to 15 minutes, but no effect.

Thanks

Mike
